This invention relates lo .a governor throttle for use iii connection with internal combustion'engines audit isaufobject of the invention to provide a devicey of' this ltiiid adapted to be iiiterposed-i'n they intake for the motor and' which operates to niaintain uniform the .motor speed wit-hthemotor under oi' freeof load. l l I ,Another obiect of the invention is to vprovide a` device .of this lriiid which may be Y "quickly installed and i'vhicli eiiibodi es a valve member mounted in` ainanner wliereby'suoh member automatically moves to regulate the amount of explosive mixture drawn from the carburetor into. the manifold andthere- 'by effectively governing Vthev motor speed.vv

The yinvention consistsin the details vof construction and in the coinbiuationaiid: arrangement `of' the several parts rof my iinfproved governor throttle whereby certain important advantages are attainedan'dvthe device rendered siinplenfless expensive and otherwise morciconvenient and advantageous for use, as will be liereiiiafterinore ,fully )set forth. u A o The novelfeatures of iiiy'invention will hereinafter be delinitely`claimedyk In order that my invention may bebettei:

Figure 5 is a sectional view taken substantially on the line 'p-'of Figure 2, 'My improved throttle, as herein disclosed, comprises a Casi-ng C consisting of two super;

imposed plates .lY readily separable to facili-v.` tate the desired assembly of all the parts,

These plates l are maintained in assembled relation when the device -is'in applied or working [position through -the medium `of the'bolts 2 which pass through the end open-`A` ings 3 in the plates l and through the op! `posed flanges 4L ofthe intake A and the car' buretor B, it being understood that my iniproved throttle when in appliedor working proved rthrottle asiherein disclosed, one.

This yshaft 9 is suitably ysupported for rocking movement.

between the asseiiibledjplates l and atits C." The rod Mat the discharge side of the casing C has fixed theretojan outstanding annularilaiige or washer. `15 and freely mounted on tlie'rod ift within thegcasing C,

or,y more particularly the chamber A7|,Yis a washer 1,. u u

" Surrounding the portion of the rod 14;

within the casing C is an expansible coil springllS, one end portioiijof which being;

fixed to the washer irland the opposite end portion to thewasher l16. also disposed through the fork l2 and serves as a screw whereby thevalve member 1lr may be setl for different speeds. This spring, when fully compressed by the arm 8 serves carrying u a disk-like f This spring is Y tostopthe valve member 11 from entirely closing. Tt will ralso be understood that the spring 8 servesto normally maintain lthe valveiii-einber'l-l in kits fully open position in.- accordance with the adjustmentof the arniS asaccomplished by rotation of A Infotherwords, upon turning the rod le as' through thebu'ttofn 17,tliearin 8 will be moved to set the valve member 11 closer to or further from the discharge opening 6 of the,

` ing openings through which the explosive the casing. When it is adjusted close to the discharge opening, the Vvalve member will more easil move under the pulsations of the motor an of course, the further away the valve member is adjusted, the` harder it will be to effect such operation.

The rod 14 extends exteriorly of the casing C and carries a button 19 and by exerting pressure on the button 19, the valveA Amember 11 may be maintained fully open should it be desired to permit excessive motor speed for a comparatively short period of`time.

From the foregoing description it is thought to be obvious that a governor throtf formation ofthe several parts 'herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim 1. In combination with the intake of an internal combustion motor, a casing interposed therein and provided with a valve chamber, opposed walls of such chamber havmixture is adapted to pass, a valve within the chamber and supported forl movement toward and from the eduction opening of the casing, said casing having a second chamber, a shaft rotatably supported by the casing and extending through said second chamber, a rock arm carried by the shaft and extending within the 'first chambena valve carried by said rock arm'for coaction with the eduction opening of said first chamber, a second rock arm caried by the shaft and arranged within the second chamber, and a tensioned member within the second chamber coacting with the second rock arm Vfor normally maintaining the valve at its limit of movement away from the eduction opening of the first chamber7 said tensioned member also serving as a stop to prevent the valve moving'to a full closed position with respect to the eduction opening of the first chamber. 12. In combination with the intake of an internal combustion motor, a casing interposed therein and provided with a valve chamber, opposed walls of such chamber having openings through which the explosive mixture is adapted to pass, a valve Within the chamber and supported for movement toward and from the eduction opening of the casing, said casing having a second chamber, a shaft rotatably supported by the casing and extending through saidy second chamber, a rockarm carried by the shaft and extending Within the first chamber, a valve carried by said rock arm for coaction with the eduction opening of said first chamber, a second rock arm carried by the shaft and arrangedwithin the second chamber, a rod disposed through the casing and the second 'chamber therein, said second rock arm having a fork straddling the rod, and a coil spring encircling the rod and engaging within the fork to normally maintain the valve atits limit of movement away from the eduction opening of the first chamber.

3. In combination with the intake of an internal combustion motor, a casing interposed therein and provided with a valve chamber, opposed walls of such chamber Ahaving openings through which the explosive mixture is adapted to pass, a valve within the chamber and supported for movement toward and from the eduction opening of the casing, said casing having a second chamber, a shaft rotatably supported by the casing and extending throughsaid second chamber, a rock arm carried-by the shaft and extending within the first chamber, a Valve carried by said rock arm for coaction with the eduction opening of said first chamber, a second rock arm carried by the shaft and arranged within the second chamber, a rod disposed through the casing and the second chamber therein, said second rock arm having a fork straddling the rod, and a coil spring encircling the rod and engaging within the fork to normally maintain the valve at its limit of movement away from the eduction opening of the firstk chamber, said rod having endwise movement through the casing and having an outstanding flange withinthe second chamber with 'which the spring engages.

4. A casing adapted to be interposed within the intake of an internal combustion engine, said casing being provided with a valve chamber having an inductionV opening and an eduction opening, a valve within the casing and supported for movement toward and from the eduction opening of the casing, a rock arm associated with the valve member and provided with a fork, a rod slidably disposed through theV casing and through the fork of the arm, a coil spring surrounding the rod Within the chamber of the casing and engaging the fork of the arm, said spring serving to constantly urge the valve member away from the eduction opening, said spring upon rotation of the rod adjusting the normal position of the valve member with respect to the eduction opening.

In testimony whereof I hereunto aix my signature.
